I-Lactic Acid | 598-82-3
Incazelo Yemikhiqizo
I-Lactic Acid iyinhlanganisela yamakhemikhali edlala indima ezinqubweni eziningana zamakhemikhali ezinto eziphilayo.Eyaziwa nangokuthi i-acid yobisi, iyinhlanganisela yamakhemikhali edlala indima ezinqubweni eziningana zamakhemikhali ezinto eziphilayo.Ezilwaneni, i-L-lactate ikhiqizwa njalo isuka ku-pyruvate nge-enzyme lactate dehydrogenase. (LDH) enqubweni yokuvutshelwa ngesikhathi semetabolism evamile nokuzivocavoca. Akukhuphuki ekugxiliseni kuze kube yilapho izinga lokukhiqizwa kwe-lactate lidlula izinga lokukhishwa kwe-lactate elilawulwa yizinto eziningi ezihlanganisa: Izithuthi ze-Monocarboxylate, ukugxila kanye ne-isoform ye-LDH namandla oxidative wezicubu. Ukugcwala kwe-lactate yegazi kuvame ukuba ngu-1-2 mmol/L lapho uphumula, kodwa kungakhuphukela ngaphezu kuka-20 mmol/L ngesikhathi sokuzikhandla okukhulu. Ngokwezimboni, ukuvutshelwa kwe-Lactic Acid kwenziwa amagciwane e-Lactobacillus, phakathi kokunye. Lamagciwane angasebenza emlonyeni; I-asidi abayikhiqizayo ibangela ukubola kwamazinyo okwaziwa ngokuthi ama-caries. Kwezokwelapha, i-lactate ingenye yezingxenye eziyinhloko ze-Ringer's lactate noma isixazululo se-Ringer's lactated (CompoundSodium Lactate noma Isixazululo sika-Hartmann's e-UK). Lolu ketshezi olufakwa emthanjeni luqukethe i-sodium ne-potassium cations, ene-lactate ne-chloride anions, exazululweni elinamanzi acwebile ekugxilisweni ukuze kube yi-isotonic uma kuqhathaniswa negazi lomuntu. Ngokuvamile isetshenziselwa ukuvuselela uketshezi ngemva kokulahlekelwa igazi ngenxa yokulimala, ukuhlinzwa, noma ukulimala kokusha.
Isicelo
1. I-lactic acid ine-antiseptic enamandla futhi igcina umphumela omusha. Ingasetshenziswa ewayinini lezithelo, isiphuzo, inyama, ukudla, ukwenza ikhekhe, imifino (umnqumo, ikhukhamba, i-pearl anyanisi) i-pickling kanye ne-caning, ukucubungula ukudla, isitoreji sezithelo, ngokulungiswa kwe-pH, i-bacteriostatic, impilo yeshalofu ende, isithokelo, ukulondolozwa kombala. , kanye nekhwalithi yomkhiqizo;
2. Ngokuphathelene nesinongo, ukunambitheka okumuncu okuyingqayizivele kwe-lactic acid kungandisa ukunambitheka kokudla. Ukwengeza inani elithile le-lactic acid kumasaladi afana nesaladi, i-soy sauce kanye noviniga kungagcina ukuzinza nokuphepha kwama-microorganisms emkhiqizweni ngenkathi yenza ukunambitheka kungabi lula;
3. Ngenxa ye-asidi emnene ye-lactic acid, ingasetshenziswa futhi njenge-ejenti emuncu ekhethwayo yeziphuzo ezithambile ezithambile namajusi;
4. Lapho uphisa ubhiya, ukwengeza inani elifanele le-lactic acid kungalungisa inani le-pH ukuze kuthuthukiswe i-saccharification, kusize ukuvutshelwa kwemvubelo, kuthuthukise ikhwalithi kabhiya, kwandise ukunambitheka kukabhiya futhi kwandise ukuphila kweshalofu. Isetshenziselwa ukulungisa i-pH otshwaleni, i-sake kanye newayini lezithelo ukuvimbela ukukhula kwamagciwane, ukuthuthukisa i-asidi kanye nokunambitheka okuqabulayo.
5. I-lactic acid yemvelo iyisithako semvelo esitholakala emikhiqizweni yobisi. Inokunambitheka kwemikhiqizo yobisi kanye nomphumela omuhle we-anti-microbial. Isetshenziswe kabanzi ekuhlanganiseni ushizi we-yoghurt, u-ayisikhilimu nokunye ukudla, futhi isiphenduke i-agent emuncu yobisi ethandwayo;
6. I-lactic acid powder iyi-conditioner emuncu eqondile yokukhiqiza isinkwa esishisayo. I-Lactic acid iyi-asidi yemvelo evutshiwe, ngakho ingenza isinkwa sihluke. I-Lactic acid iyisilawuli semvelo sokunambitheka okumuncu. Isetshenziselwa ukubhaka nokubhaka esinkwa, amakhekhe, amabhisikidi nokunye ukudla okubhakiwe. Ingathuthukisa izinga lokudla futhi igcine umbala. , andise impilo yeshalofu.
7. Njengoba i-L-lactic acid iyingxenye yezinto zemvelo zokuthambisa zesikhumba, isetshenziswa kabanzi njengesithako semikhiqizo eminingi yokunakekelwa kwesikhumba.
